摘要： An anti-jerk control system and method of an eco-friendly vehicle are provided to prevent a driver from sensing a difference in vehicle starting at an initial stage when the vehicle is parked on a downhill road. The anti-jerk control method uses a motor as a driving source and includes calculating an actual speed of the motor, calculating a model speed of the motor, and acquiring a gradient of a road, on which the vehicle is located, using a gradient detector. Additionally, the method includes determining a speed offset value that corresponds to the acquired gradient, compensating the model speed by the speed offset value, and calculating a motor vibration component using a difference between the compensated model speed and the actual speed of the motor. Then, anti-jerk compensation torque is calculated using the calculated motor vibration component.

摘要： A system for controlling a lock-up of engine clutch may include an engine and a motor; the engine clutch mounted between the engine and the motor and configured to selectively transmit power of the engine between the engine and the motor; a hybrid starter generator (HSG) connected to a crank pulley of the engine and driven to start the engine; and a controller connected to the HSG and configured to determine a virtual engine speed in an engine firing process and a torque reduction ratio of the HSG according to the virtual engine speed after an engine cranking process and determine a correction reduction ratio with respect to the torque reduction ratio of the HSG using a difference value between the virtual engine speed and an actual engine speed, and adjust an increase or a decrease of the torque reduction ratio of the HSG to synchronize an engine speed with a motor speed for the lock-up of the engine clutch.

摘要： An apparatus and a method for controlling a driving mode of a vehicle are provided. The apparatus includes a mode converter that converts the driving mode of the vehicle based on an operation of a mode conversion input. When the driving mode is converted into a custom mode, a mode setting screen for adjusting a setting value of a driving characteristic preset is configured and the configured mode setting screen is displayed on a display of the vehicle. A tuning device then tunes a driving characteristic of the custom mode based on a setting value adjusted on the mode setting screen.

摘要： Provided is a method of controlling a hybrid electric vehicle capable of improving acceleration response upon kick-down. The method includes calculating a rising gradient of a motor speed increasing during kick-down shift based on a present speed of a motor for driving the vehicle which is detected at a control unit in real time, upon detection of demand of kick-down shift due to acceleration operation of a driver, calculating a falling gradient of intervention torque based on the rising gradient of the motor speed at the control unit, determining an entry point of intervention control based on the present speed of the motor detected at the control unit in real time, and performing torque intervention control for controlling driving of the motor in order to output intervention torque, namely, motor torque decreased based on the falling gradient of intervention torque calculated from the determined entry point at the control unit.
